Calyxos user here. I like it so far. Half a year into it. I can live with microg instead of gms.

I use Opensuse leap. It works for me. If i cant find software i want i use the nix package manager

I whould use windows 8.1 but iyhbwont receive updates anymore. Otherwise good. Use openshell for a real start menu

Su Linux is most likely the answer to lering younger people to use computers fedora is especially good becouse it has a nice package manager (dnf) that is easy to understand
